Abstract

Compact high-speed electro-optic modulators are key to next-generation optical transceivers for exa-scale data centers and large-scale artificial-intelligence (AI) clusters. As key performance metrics, the devices must combine large modulation bandwidth and low optical loss with compactness and low-...
